Influence of pulsed electric current treatment on strength of reinforcing steel and its welds under impact loading

Abstract

Results of static and impact tension tests of as-received reinforcing steel specimens, specimens with weld joints in their test portion, as well as specimens after high-density pulse current pretreatment are presented. As test results demonstrate, an increased strain rate enhances strength, and pulse current treatment greatly influences the strength and plasticity of a defect-containing weld metal under static and impact tension
